"I found out Nareesha was planning a surprise party on my birthday with her family so I thought [it was] perfect," Kaneswaran told the U.K.'s Hello! magazine. "I'd bought the ring months before I'd been trying to figure out the right time."

As for his absolutely tear-inducing proposal, Kaneswaran turned the tables on his unsuspecting love.

"I said to her I wanted a present I would always remember this year by...for you to be my wife," he said. "It was like a military operation to plan the proposal. I couldn't even tell the other boys in the band in case they blew the surprise."

"I love her, I love every bit of her," Kaneswaran added. Though she obviously echoed his feelings by saying yes, she wasn't totally thrilled by her surprise engagement. According to Kaneswaran, he almost fainted when McCaffrey initially said a quick no—luckily, she had a (somewhat) good reason for doing so.

"I don't like surprises and he really surprised me, but I was so happy," she says. "I can't wait to start planning the wedding."
